• 1. Section 1.4 Lines
• 2. OBJECTIVE 1
• 3.
• 4.
• 5.
• 6.
• 7. Find the slope of the line containing the points ( – 1, 4) and (2, – 3).
• 8. Adjust the selections for X min, X max, Y min, and Y max by setting the ratio of x to y at 3:2.
• 9.
• 10.
• 11. These figures also illustrate that the closer the line is to the vertical position, the greater the magnitude of the slope.
• 12. OBJECTIVE 2
• 13. Draw a graph of the line that contains the point (1, 4) and has a slope of:
• 14. OBJECTIVE 3
• 15. Graph the equation x = – 2
• 16.
• 17. OBJECTIVE 4
• 18.
• 19. Find the equation of a line with slope – 3 and containing the point ( – 1, 4).
• 20. Find an equation of the horizontal line containing the point ( – 4, – 1).
• 21.
• 22. OBJECTIVE 5
• 23. Find an equation of the line L containing the points ( – 1, 4) and (3, – 1). Graph the line L .
• 24. OBJECTIVE 6
• 25.
• 26.
• 27.
• 28. OBJECTIVE 7
• 29. Find the slope m and y -intercept b of the equation 3 x – 2 y = 6. Graph the equation.
• 30. OBJECTIVE 8
• 31.
